Title: Improvements in or relating to signal producing systems for lift control
IPC: G05B19/07
Filed: 1961-08-18
Abstract: 929,419. Automatic speed control. KOEFOED, HAUBERG, MARSTRAND & HELWEG AKTIESELSKABET TITAN. Aug. 18, 1961 [Aug. 19, 1960], No. 29940/61. Class 38 (4). [Also in Group XL (c)] In a retroactive speed control system for a lift, a reference voltage is developed across terminals b and o by means of an emitter earthed transistor Tr1 followed by transistor stages Tr2, Tr3, arranged as emitter followers. Means for integrating a step function voltage which is applied to transistor Tr1 comprises capacitor C connected between the base of transistor Tr1 and the emitter of transistor Tr3. The lift is stationary when a high negative potential is applied to the base of transistor Tr1 from potentiometer P2 to render the transistor conductive. Closure of switch K1 reduces the base current of transistor Tr1 so that the potentials at terminals a and b become negative. Due to the capacitor C, the reference voltage rises in linear relation to time, the lift being accelerated and continuing at constant speed until the switch K1 is reopened. The reference voltage then falls linearly to provide deceleration until the lift is stopped. The operation of deceleration may be discontinued to afford inching speed by closing switch K3 to connect potentiometer P3 through blocking diode d3 to the base of transistor Tr3. A speed intermediate between the inching speed and normal travelling speed is obtained by closing switch K2 to connect potentiometer P4 to the base of transistor Tr2 through blocking diode d2, the switches K1 and K3 being open. A resistance-capacity network may be connected across terminals o and b. The system may comprise two signal-producing circuits which are coupled together in a mirror-turned relation, with a common supply voltage, and with their output signals in opposition, for controlling upward and downward movement of the lift.

Title: A process for the refining of sugar juice by chlorination
IPC: C13B20/08
Filed: 1924-12-15
Abstract: 249,191. Ochi, S., and Kotera, F. Dec. 15, 1924. Purifying succharine liquids. - Cane, beet, or other sugar juices, or raw sugar liquor, are refined by first chlorinating at a temperature of not more than 55‹ C., removing the active chlorine by means of activated charcoal, and then neutralizing the treated juice by adding an alkaline substance. The chlorination may be effected by blowing in chlorine gas, or by passing an electric current, e.g. between platinum or graphite electrodes, through the juice which has previously been mixed with a chloride, such as radium chloride, or by the addition of a chlorine solution e.g. an aqueous solution, on one prepared by adding an acidic substance, such as chlorine or carbon dioxide, to a solution of bleaching powder &c. containing active chlorine, or by dissolving chlorine in a solution of an alkali, such as lime. The neutralization may be effected by adding an alkaline substance, such as an oxide or carbonate of an alkali or alkaline earth metal or ammonia. In one method, raw sugar, which may first be washed with water to remove molasses, is dissolved in warm water and chlorine gas is blown in with constant stirring at a temperature of 20‹ C., the solution being rapidly bleached. Activated charcoal is next added to remove the free chlorine, and the solution then neutralized with caustic soda and evaporated in a vacuum. Care is taken that the solution does not become alkaline. Filtration through charcoal may be combined with the bleaching step. The treated juice may be subjected to sulphitation and carbonation.

Title: Divider circuits
IPC: H03K21/00
Filed: 1974-07-09
Abstract: 1460421 Transistor pulse circuits SMITHS INDUSTRIES Ltd 20 June 1975 [9 July 1974] 30388/74 Addition to 1334131 Heading H3T A divide by two circuit similar to the parent Specification 1,334,131 has three switch means in which the first two A, B are both switched to their second state by the start of a first input pulse at 41 and A reset by the end of this pulse and in which the third C is switched to its second state by the start of a second input pulse, causing B to be reset, and the finish of the second pulse resetting C. The switches, as before, can be a regeneratively coupled pair of transistors (Fig. 2, not shown) one being lateral PNP, the other vertical NPN. No connection is required to the base of the NPN in this modified circuit. The rising edge of the input pulse is applied to A30 to turn A on, effectively grounding A15 to turn B on, this causes the output 42 to fall (Fig. 4, not shown) but not far enough to turn C on, A30 being pulled low by A, to about 1 volt above 21. B15 is held lower than B30 so that at end of the first pulse B stays on while A is turned off. The rising edge of the second pulse takes C30 above C15 and turns C on, thereby pulling C15 and hence B30 and the output even more negative, below the voltage at B15, to turn B off. C is turned off at the falling edge of the second pulse. Thus a full rising edge is generated at 42 for every second input, the fall being in two steps. An extra resistor (32, Fig. 5, not shown) can be added to eliminate the need for the second voltage V/2.

Title: Process for the catalytic hydrogenative refining of hydrocarbon wax
IPC: C10G73/44
Filed: 1961-08-24
Abstract: Hydrocarbon waxes from high boiling hydrocarbon mixtures, including those obtained by de-waxing lubricating oils, are catalytically hydrofined by contacting the wax in the presence of a hydrogen-containing gas with a tungstennickel sulphide catalyst at a temperature not above 360 DEG C., preferably at 250 DEG -300 DEG C. for distillate waxes and 300 DEG -350 DEG C. for residue waxes and at a pressure above 40 atmos. abs. and preferably above 80 atmos. abs., the atomic ratio W:Ni in the catalyst being 3:1 to 1:3, and most suitably about 2:1.  The catalyst may also contain iron sulphide, the amount of which is less than 25%, and preferably less than 10% by weight of the catalyst (both calculated as metal).  The wax to be treated most suitably contains less than 5% by weight of oil and is most conveniently treated in the trickle phase, being passed over the catalyst bed at a liquid hourly space velocity of 0,5-5, preferably 0,7-2, kg./hr./litre of catalyst and at a gas:wax ratio of 100-1000, preferably 200-500, litres (S.T.P.)/kg. wax; the gases used should contain more than 60%, and most suitably more than 85%, by volume of hydrogen.  The catalyst is most conveniently used when supported on a carrier such as active carbon, fuller's earth, kieselguhr, pumice, bauxite, burnt clay or, preferably, alumina; the weight ratio of the catalyst to such a carrier is suitably 1:4 to 2:3.  The carrier is impregnated with a solution of a mixture of salts of tungsten, nickel and, if required, iron to form a paste, the resultant material is dried, pelletted with stearic acid, the stearic acid burnt off in the presence of oxygen, the product calcined at 500 DEG C. to the oxides, reduced with hydrogen to the metals, and finally sulphided by treatment with hydrogen sulphide or other sulphur compounds, with or without hydrogen, at 10 atoms, abs. and 100 DEG C. rising gradually if desired to 250 DEG -450 DEG C. Iron-containing catalysts may be obtained without separate addition of iron by using a ferriferous carrier.  Alternatively the catalyst may be produced unsupported (1) by treating a suitable mixture of the metals, the oxides or the hydroxides with hydrogen sulphide, sulphur, carbon disulphide or another sulphur compound, or (2) by producing the sulphides separately and then mixing in the ratio required.  Specification 657,521 is referred to.
